Novel fluorine-containing epoxyacrylate resins and epoxymethacrylate resins have been synthesized from two epoxy resins, diglycidylether of bis(l,l,l,3,3,3-hexafluoro-2-hydroxyisopropyl)cyclohexane and diglycidylether of 4,4'-bis(l,l,l,3,3,3-hexafluoro-2-hydroxyisopropyl)diphenylether. Four synthesized resins can be cured by UV-irradiation, they show extremely low refractive indices of 1.428∼1.495 due to their high fluorine contents of 29∼34 wt%. Cured resins are highly transparent to wavelengths from 0.S to 1.6μm; they demonstrate high adhesive strengths to quartz glass, more than 85 kgf/cm2. These resins have a particular utility for the formulation of optically transparent adhesives, since they improve matching of the refractive index with that of optical glass. The adhesive composition provides very high return loss more than 40 dB at the joints of optical fibers. 1991, The Society of Polymer Science, Japan. All rights reserved.
